Dear Mathematica-users,
I have a simple question about to simplify a expression (a list/matrices). I
have a list like
{2 cet1, 0, -2 cet1, cet1, 0, -cet1}
And I want to extract if possible the factor cet1, so I become a list like
cet1{2, 0, -2, 1, 0, -1}
How can I extract the factor?
TIA and regards,
Cetin
